GALVANIZING' APPTUS.

Application filed March 1, 1922. Serial Ne. %0,102

I citizen of the United States, residing at Oalland, in the County of Alameda and State of California have invented certain new and useful Improvements in Galvanizing Apparatus, of which the following is a specification. 4

My invention is an improved galvanizing apparatus, particularly useful for galvanizing wire screens, which is simple in Construction and highly ecient in operation.

Referring to the annexed drawing in which my invention is iilustrated and which forms a part of this specification:

Figure 1 is a plan view of my galvanizing; apparatus.

- igure 2 is a longitudinal vertical section of my apparatus. ,In the drawing 1 indicates' a tenk preferably for-med of Wood, which contains a galvanizing solution, and 2 indicates a wooden frame detachably mounted in said tanko Said rame includes two bars 3-3, two walls 1- 1 depending respectively from said bar two connecting members 5 and 6 joining the walls 4-4, and four metallic connecting rods 7, 8, 9 and lO are also spaccd r between said walls. The connecting member 5 connects at its ends to the lower part of the walls H midway of their ends and the connecting member 6 connects to the walls 4-4 a short distance above the member 5.' The rods 7 and 8 connect to the walls 4--4 near their upper left corners. The rods 9 and 10 connect the walls 4--4 near their upper right corners. On opposite sides of the connecting member 5 are formed ledges 11 and 12 on which rest the lower ends of a plurality of arcuate zine anodes 13 and 14: respectively,` arranged side by 'side a short distance apart, the upper" edges of -said anodes being sus ended-by their hooks 15 and 16 respective y on the rods 7 V and 9 respectively. On opposite sides of the connecting member 6 are ledges 17 and 18 on which rest thelower ends of a plurality of arcuate zinc anodes 19 and 20 respectively arranged side by side a short distance apart, the upper ends'of said anodes being suspended by their hooks 21 and '22 respectively on the rods 8 and 10 respectively.` Wooden rollers 23 and 24 are journaled between the connectin members 5 and 6 on shafts 2'5 and 26 secur at their ends in the walls 4:-4,

said connecting members being ooved to receive half of said rollers. pair of wooden rollers 27 and 28 are journaled between the uppe-r ends of the cathodes 13 and 19 on rods 29 and 30 which are Secured at their ends in the walls-. A pair of wooden rollers 31 and 32 are journaled between the anodes 13 and 19 intermediate the` ends of said anodes on rods 33 and 34; which are Secured at their ends in the walls 4-4. A pair of wooden rollers 35 and 36 are journaled between the upper ends of the anodes 14 and" 20 on rods 37 and* 38 which are Secured at their ends in thewalls -d. A pair of wooden rollers 39 and 40 are journaled between'the anodes 14 and 20 intermediate the ends thei-cof on 'ods 41 and 42 respectively which are Secured at their ends in the walls 4-4. A metallic roller43 is securedon a shaft 4 1 journaled in brackets 45 mounted on the left ends of the bars eaf 3-3. A metallic roller 46 is Secured on a shaft 47 journeled in brackets 48 mounted( on the right ends ofthe bars 3--`3.-

1`he negative lead 50 of an electric circuit is connected to the roller shaft 4:& Leads' 51 and 52 are' connected to rods 7 and 8 respectively and to a lead 53. Leeds 54 and- 55 are connected'to rods 9 and' 10 res ec-' tively and to lead 53.. The positive ie 56 of the circuit is connected tolcad 53.

The screen'O to be galvanized is fed over the roller 43 between the rollers 27 and 28, 31 and 32, 23 and 24, 39 and &Oy-and 35 and 36, between the cathodes'13 and '19 and the anodes 14 and 20 and over the roller 46.' The screen forms the cathode as it passes through the apparatus and the zine of the anodes 13 and 19 and 14 and 20 is deposited on the screen and the screen is galvanzed.

The frame 2, and the parts mounted thereon including the &modes 13, 19, 1 1 and 20, may be removed from the tank and the anodes may be readily removed from the treme.

Having described my invention, I claim:

1. A galvanizing apparatus including a tank, sets of anodes Suspended in said tenk in superposed space'd relation, a plurality of rollers arranged in pairs in the s ace be-, tween'the sets and journaled in said tank, between which rollers the material to be galvanized is fed.

2., A galvanizing apparatus including a tenk, a frame detachably mounted in said tmk, said frane including a pair of super imposedi cross members in the lower part' 'Suspended at their upper enls on a, pair; of

said cross rods and Testing at their %Wer ends upon tha appear cross member, another pair of modes suspendedi'n %she other &two cross EOdS at *their rapper endls and Testing a& their lower ms on said upp@ Cms@ member reflers arranged in pem 30111 11316& in sai& frame bem/'een said anoes, between Whichfdhe .material to To@ galvaniz d is fe, and sa ?oher on each end 'of said iframe over which the material extend&
